巩膜隧道切口白内障囊外摘除及人工晶体植入术

Scleral turnnel incision extracapsular cataract extraction and intraocular lens implantation

报告57眼行巩膜隧道切口白内障囊外摘除及人工晶体植入术的观察结果。患者年龄8～81岁（平均59岁）。术后一周矫正视力≥0.5者29眼（50.9％）；术后三月矫正视力≥0.5者51眼（91．1％），矫正视力＞1．0者34眼（59．6％）。木后角膜表面屈折力变化垂直径线大于水平径线。术后散光呈现循规性改变，统计学分析术后一周（1．43±0．83D）与术前（0．64±0．56D）比较有显著性差异（P＜0．01），一月后与术前则无显著性差异。术中和术后并发症减少。结果表明，巩膜隧道切口优点为手术切口小、切口闭会好、术后反应轻微、术后激光小、术后视力恢复快而稳定。

The results of 57 eyes scleral turnnel incision ex tracapsular cataract extraction and intraocular lens im plantation were reported. The patients ages ranged from8 to 81 years, averaging 59 years. Postoperatively, thecorrected visual acuities of 0. 5 or better were achievedin 29 eyes (50. 9%) at one week and in 51 eyes(91. 9% )after 3 months, 1. 0 or over in 34 eyes (59. 6% ) after 3months. There were diminished intra - and post - oper-ative complications. The postoperative astigmatismshowed a tendency of with - the-rule. Statistical analyses showed that the differences between preoperativeand one weed after surgery were significant (P < 0.01 ). The defferences between preo - and postoperativeone month were no statistically significant. The resultssuggest that advantages of scleral turnnel incision aresmall incision better incision closed -slight postoperativereaction,less induced astigmatism and fast visual reha bilitation inherent.
